Be it known that I, lJESSE G. VINCENT, a

citizen of tlieUnited States, residing at De' troit,- in the countyof Wayne and State of 'Mlehigan, have invented certam new and useful' Improvements in .Addlng-Macliines,

i ofwhiclrtlie following is a s ecification.

The presentr invention're ates more particularly to thatl typel of adding and listin' 10 machine in which accumulator inions an vtheir,actuatingracks are en age and disengaged 1n varying periods of t e Inaclimes opcrat1on,"according\to whether itemizing, to-

I

The principal objectol the present inventionls to do away mt; the. necessity forreleasnig the manipulatiwA means ata certain eit isv customary.

stage in the operation of the machine when a subtotal is desired and to provide additional manipulative means for p reventing the auto- -matic action abovementioned whereby the scribed manipulative means, but also to provide for locking sail means against return fafter manipulation once the machine has started upon a totalizing operation and until tnat operation .is completed.

` Another object attained by the present in'- vention is the .provision of means for reventing adjustment of connections for ta ing a subtotal after manipulation li as started for the taking of a grand total and vice versa,

With tixese and incidental objects in view, the invention consists of certain novel features of construction and combinations of parts the essential elements whereof are recited in theap ended claims and a-preerred form of embodiment of which is described in Vdetail hereinafter and fully illustrated in the accompanyingA drawings forming part of this specification.

Of said drawing, Figure 1n represents in `left side elevation the interior parts of an adding and 'listing machinev of the well known Burroughs type with the present iml provementsap lied thereto, the,casing and certain cross siafts and studs appearing-in section, as well as parts of the paper carrying attachment; Fig. 2 similarly represents on an enlarged scale the parts more particularly concerned with the present invention, the same being represented relatively positioned as when the totall key has been .(lepressed, dotted lines representing further change in relative'. positioning when an operation of the machine hasv been started.; Fig. 3 is a similar view representing the rela-tive positioning of vparts when the j su'btotal key is depressed and {Figf 4f-is`"a"fragmentary right side elevation; ,of the interior parte ofthe `machine asthey. appear: at normal-.v

By preference the'j invention v'has @been illustratedv as appliedtofthegwellknown i` Burroughs adding machine but. i'tlis -tof'ba understood that it. is applicable to other amount keys and the numeral 610 segmental racks whose extent of movement is determined by stops set by said keys. Small gear wheels or pinions 916 are arranged to mesh with these racks respectively and are compounded with numbered wheels 999 which accumulate the amounts set up on the keyboard. Said pinions and number wheels are ca rried in a rocking frame having end plates 910 one of whichextends below Athe pivot rod 900 and carries inwardly projecting studs or p ins'958 and 9584 one-above and the other below said rod. A itman 914 is branched at the forward end or engagement with these pins,or studs and at its rear end connects with a three-armed lever 913 carrying studs or pins 961 arranged to be alternately acted uponby a wipe pawl 821 on the upper end of an arm 813 secured to a rock shaft 800. The latter is oscillated in 'every operation of the machine and through the devices described the pitman is reciprocated. The latter is connected through a link 911 with a bell crank lever 227 constituting the total key and normally upheld by a suitable sprin 282. So .long asthis total key is so uphe d the reciprocations of the pitman have the effect of removing the accumulator pinions from engagement with the racks at the outset of an operation of the machine and then urestoring said pinions to mesh with said racks after the latter have lowered to the extent permitted by depressed amount keys and before the return of said racks to normal. This is due to the fact that normally the stud or pin 958a rests in a notch of the upper. branch of the pitman'. Depression of the total key lowers the pitman and destroys this operative connection so that when the pitman is thrust forward .as the machine starts to operate the accu- -mulator racks.

inions remain in mesh with the he lowering of the pitman in this manner brings the forward extremity of its lower branch into position for engagement with the stud 958so that when the pitman' moves rearwardly it will'rock the accumulator frame and disengage the pinions from the racks before the return latter commences. e v

It will be noted that the link 911 is formed mov ement of. the

The reference numeral 291 designates the usual.

l at its upper end with a longitudinal slot 911L and that the total key lever 227 carries a' screw-stud 227a Aengaging said slot. This stud normally occupies the u )per end of the slot and when the total lever 1s depressed for a totalizing operation the link and pitman n simply travel down with vitb their own weight supplemented by a spring 981 connecting the link -with the arm 813. This has'the effect of .bringing the hooked end 914:b of the lower branch of the pitman to rest upon thc top of the lower stud 958, as shown in 2. When thc pitman moves forward this hooked end will drop over said stud as shown by the dotted lines in Fig. 2, owing to the above mentioned slot-and-pin connection between the Alink and the total lever. f Therefore unless the lever is meantime released and permitted to rise carrying with it the link and pitman the hooked end of the latter will u on the rearward movement thereof take rock the accumulator pinions out of mesh with the racks. ln machines of the above description as heretofore employed it has been customary to preserve engagement between'the racks and pinions for subtotal pur- 1oses by simply releasing the total key or ey lever before the rearward movement of the pitma'n takes place. By the present invention it is proposed to prevent the hooked old of the stud 958 and' end of the pitman from ropping in front of Itotal lever is of bell crank form, the same as the other lever, and to its depending arm there is pivotally connected the rear end of a bar 216 which. extends forward alongside of thedepending arm of the other bell crank lever and alongside of the link 911. forward end of this bar is slidingly supported upon a cross rod 202, the bar being longitudinally slotted as at 216a to embrace said rod and furthermore notched at opposite ends of the slots in the upper side there of,as shown at 216b for the purpose of engaging thegcross rod in such manner as to detain the bar in either of its two adjustments. In furtherance of this desigrfa spiral spring 281 connects'the forward end of the bar with. a fixed stud so as to enforce the engagement between said notches and said cross rod. The bar 216- is formed on its under side about midwa .its length with a depending lug216c whic normally stands immediately in front ofa laterally projecting stud 227 on the depending arm of the bell crank 227 as shown in Fig 1, this arm ofthe bell crank being as usual drawn for ard by the Aspring 282 which f operates to upholcthe link 911. and pitmalrv 914. Depression of the subtotal key lever iso sin

227s has the effect of drawing rearwardly the,V bar 21`b`-and throughthe action oi the lug 216? upon the stud 227c of depressing the total lever and causing lowering of the link 911 and of the pitman as illustrated in Fig. 3.- "lhis is practically" the same eifect produced -bydirect depression of the. totallever 227, the differencev being that the hooked end of the p-itman does not come-to vrest upon the stud 9,58 and the pitman is prevented from dro )ping so as to engage the front side of. sai stud. This is accomplished as follows: The link`911 carries alaterally projecting stud 950 a short 'distance belovsT the slot 911% 15 and. the bar 216 at the forward portion is f `adapted to pass under 'said stud when the bar moves -1-earwardly, thereby preventing the such as otherwise permitted by the slot-endl pin connection before mentioned. This particular part of the bar terminates in an abrnpt transverse shoulder 2161, the bar being y notched immediately behind said shoulder to receive the stud 950 when' the total lever is" directly depressed, see dotted lines Fig. 2. It Willbe'see'n that the lowering of the 'link by' directv depression ofthe total lever 227.- re' sults in locking the subtotal lever against de-k pression by reason of the stud 950 taking up 3o a position in rear ofthe shoulder 2161. Of course such depression v of the tota-l lever has no effect to move the subtotal lever, the stud 227c simply retreating from the lug` 216. The above described arrangement WilLbe seen to do away with release of the total key leverat an intermediate stage ofthe ma- -ehines operation when a subtotal is to be taken.. ConsequentlyV this' lever can be' Vlocked downduring the entire operation of the machine and does not require to beheld downv by the operator. familiar oscillatory sector 311 of the Burroughs machiney (Fig. 4) carries on one side a curved locking strip 315 and the well known rock shaft 1400 carries a depending arm 1.414 equipped at its lower end with a rollerstud "l 14351 normally standing j ust beyond the -iorv"end ol .the lock str1p315 on .the inner iereoi'. A' short crank arm 1410 on ek' shalt 140() is connected by alink with the depending arm ol' the'bell vv'crank lever 227 or with a companion arm. 227b at the opposite-side of the machine and itwill be seen' that the rocking of this lever when setting the parts for taking either a f total o r subtotal will result in carrying the fro' frlstud 1435 across the end of the lock 5 to the front side of the latter.

achines starting to operate theY lock Ynis .instantly carried behind the roller 'stu 'and it is made suiiiciently long to rcmainbehind saidxstud when the sector 311 reaches the limit el its initial stroke. Cen" se uently the total connections will runnin ed until the sorter returns lo unravel,

To this end the Upon Obviously -vifhen. neither total key -is de-l pressed andthe -ncar'slline is operated the lock strippassesin front of the, roller stud, remam'ing there .thronghoutt e operation of .the machinef-andfpreventing any manipulation of either total' key.

Thetotal levers are' preferably operated y means 'of key ybuttons 293' and 293s mounted rspectivelyfupon stems forming parts of the levers and arranged 'to slide through 'the keyboard plates.4 The bell crank 227 as usual operatesa bail comprising side arms 226 and a cress'red 226l lor displacing-therack latches 415. i It will now be seen'that'the above de, scribed c onstructionsare Well calculated to- 'thoroughly fulfil; the objects" rimarily state'c'lj` jAt the same time it is to e understoodthat these constructions are' susceptible of modification, the invention not being limited tothe `details thereof.
